Unified RT - HTTP Error 500.0 - Internal Server Error

Dear Experts,

I was using Unified V17 upd.4  and everything was running fine,  until I install V18 TIA portal.

After installation of V18 TIA and unified runtime ,  i found my runtime giving me ( HTTP Error 500.0 - Internal Server Error.)

I tried to check and re-configured IIS features for Web service, but still facing same issue.

I uninstall V18 and V17 completely , Re install TIA + Unified V17 and found still same issue.

I am sharing screen shots for reference,  Please advice if anyone had face same issue.

Thanks

Hi Pratts23,

Your screenshot shows that your project is only partially running. I know this "partly running" state from a situation where the project itself has a bug. To make sure the problem is not project-related, you should try it with another project first.

Kind regards

 Hi Stefan,  

 you are right ,  even i thought of the same  so i  created a project with just PLC and  Unified HMI and give them connection.  My project has no codes or DB inside  still  it says partially running. Is it enough to make sure the problem is not project related ?

Hi Pratts23,

It would be easier to fix if the problem was project-related. However, since it is not, the cause of the problem may be the IIS or the WinCC Unified PC Runtime.

Since your screenshot shows a 'WinCC Unified' tab, I assume that the main Unified web application is running in IIS. If not, you can try to restart the 'WebRHPool' as rdoliveira shows.

For a runtime related problem, you should take a look at the TraceViewer. But to be honest, in most cases it's not easy to find something there if you're not experienced in reading these trace logs. Most of the time this would be a case for technical support.

Kind regards

 Hi Stefan ,  
 
Thanks for the suggestion,  i tried restarting WebRHPool ,  but the problem remains the same.

I think i have no option but to re-install windows.

Thanks

Hi Folks, 

    I installed V18 on the same PC where V16 & V17 was installed already. 

    So Installing V18 only on top of V16 + V17 will create some problem in unified simulation , and hence Siemens has released Upd.1 SR1 which can be installed on V18 directly and this works fine.

  My problem is resolved after installing V18 upd.1 SR1.

Regards, 

Pratts.
